      Turbo 900E (External 
      Modem  ) 
           The Aztech DSL900E(B) is a 
      Controller-based External ADSL bridged modem. It uses ST Microelectronics' 
      Centaur solution that fully complies to ANSI T1.413 Issue 2, ITU-T G.992.1 
      (G.dmt) and G.992.2 (G.lite) ADSL standard. It supports Full-Rate ADSL 
      transmission at up to 8Mbps downstream and up to 640Kbps upstream. 
      Furthermore, it is interoperable with major DSLAMs and support standard 
      10Base-T Ethernet interface cards. PRODUCT SPECIFICATIONS ADSL/ATM Support
